9.3 Basic maintenance schedule (users)
In the following table, the basic maintenance activities to keep the system free from troubles and avoid breakdowns are described. These
activities must be performed by trained users. The intervals for some of the tasks depend on the individual installation and must therefore
be defined by the operating company.
The position references in the table refer to the PID. See fig.
9.3.1 Cleaning the system
If necessary, clean all product surfaces with a dry and clean cloth.
9.3.2 Checking the water hardness of the softened water
We recommend to perform this check with the Grundfos
Selcoperm test kit. See section
1. Put on safety goggles.
2. Take a sample from the soft water outlet of the water softener.
3. Perform the test according to the test kit operating
instructions.
9.3.3 Checking the NaClO solution
We recommend to perform this check with the Grundfos
Selcoperm test kit. See section
1. Put on protective clothing, safety goggles and gloves.
2. Put a clean 1000 ml vessel under the NaClO solution sample
valve (V0.09).
3. Slowly open the sample valve (V0.09) and fill the vessel with
1000 ml NaClO solution to flush the sample line.
4. Dispose of the sample in accordance with local regulations.
5. Take a 50-100 ml sample from sample valve (V0.09).
6. Check the temperature and the concentration of the NaClO
solution according to the test kit operating instructions.
9.3.4 Checking the salinity of the electrolyte
1. Put on safety goggles.
2. Put a clean 500 ml vessel under the electrolyte sample valve
(V0.06).
3. Slowly open the sample valve (V0.06) and fill a clean vessel
with 200-500 ml electrolyte solution to flush the sample line.
4. Dispose of the sample in accordance with local regulations.
5. Slowly open the sample valve (V0.06) and fill a clean vessel
with 200 ml electrolyte solution.
6. Perform the measurement according to the separate manual
of the measuring device.
Observe setpoint 9 for the conductivity or setpoint 14 for the
specific gravity. See section
If the result of a check requires change, repair or
adjustment of the system, call certified service
persons.

See section
To be defined
by the
operating
company
Selcoperm electrolysis system
Clean the surfaces of the system.
Selcoperm electrolyser
Check the salinity of the electrolyte.
Weekly
Selcoperm electrolysis system
Check for leakages.
Selcoperm electrolyser
Check the flow rates of water and brine on the display.
Check the DC voltage and current values on the display.
Check the water hardness of the softened water.
Degassing and storage tank
Check the air flow of the degassing fan (EF4.01, EF4.02).
Brine tank
Check the salt level in the brine tank. Refill with salt, if required.
Gas warning system
Check that the controller (5.00) does not display any errors.
Observe
separate
manuals.
Monthly
Selcoperm electrolysis system
Visually inspect the NaClO solution line and the exhaust air line for
damages.
Visually inspect the piping of the degassing and storage tank for
damage caused by vibrations of the degassing fan.
Selcoperm electrolyser
Visually inspect the electrodes in the electrolysis cells (C1.1 - C3.2).
Check the temperature and chlorine concentration of the NaClO
solution.
Check the temperature of the DC connections of the cells on the
display.

WARNING
Electric shock
Death or serious personal injury
Liquids on electrical components can lead to electric
shock. Furthermore damage to the equipment can be
caused by short circuits.
- Keep all electrical components dry.
- Do not use water or any other liquid to clean
electrical components or electrical lines of the
system.
- Do not use a high pressure cleaner.
The salinity can be checked either by measuring the
conductivity with the Grundfos conductivity
measuring device or by measuring the specific
gravity with the Grundfos Selcoperm test kit.
